You know, you've had Jenny trump every important-for-character-development duel Jaden had fought in the actual series; I'm glad to see her finally fight her own original battle. I'm very upset that you've had an OC take over most of the main character's battles, but I also like how you had her decline the Chazz battle with North Academy.
You are balancing on that precipice between OC and Mary-Sue and only by finishing this story will I and your other readers find out which it'll end up as. I look forward to it. ;p

Hehehe, it looks like Jenny and Jaden's duel is going to be the even of the story! You know, that one thing in shows that keeps people watching to see if they can get a glimps like Sam and Danny's kiss in Danny Phantom. XD

Are you going to go far enough to have the Supreme Ruler show up?! Can't have an overpowered character like Jenny without making the other characters more powerful too, otherwise you get a Mary-Sue and no one likes those. XD
